My invention relates to a method and mechanismfor trimming and cuttingpaper stock.

Heretofore, in the laying up of paper stock and the jogging thereof toeven t e edges of the paper pile, several disadvantages have always beenpresent. One of these has been the time required. If the sheet was oflarge dimensions, it necessited the services of two operators for thehandling. The size of the sheets required that small quantities befolded over and then passed through the small space between the knife ofthe cutter and its table, and as the pile ew, the opening up of thesefolded groups ecame increasingly diflicult as the height of the pileneared the edge of the clamp, and much time was required by bothoperators before the cutting of the sheets could be resumed.

Further, the time of the second operator or helper was a total lossduringthe cutting operation, as the entire cutting operation was handledby the machine operator, the helper bein idle.

It is the object of my invention to minimize the difliculties of layingup and jo ging the paper stock by eliminating the ifiicultiesencountered by reason of the space previously required to open out thesheets as they were removed from the stock pile to the cutting table. Itis a further object to provide a machine in which the jogging of thestock is greatly facilitated.

A still further object is to dispense with the necessity of a helper inlaying up and jogging the stock.

The above objects and other advantages of my invention will be set forthand disclosed in the following specification.

Referring to the drawings Figure 1 is a perspective view of a cuttingmachine embodying my invention.-

Figure 2 is a plan view of the tables of the cutter, havingsuperimposed. upon them :1 dia ram of the electric circuits.

igure 3 is a perspective view of a slip strip for the paper stock file.

Figure 4 is a fragmentary view of the cutter showing the former methodof building the paper pile.

at 1, having a table as shown at 2, a cutter knifeas shown at 3, ahold-down 4, a side gau e 5, and amovable back gauge 6.

e machine shown is equippe with suitable driving devices and controls,all of these parts being of usual structure forming no part of myinvention. Prior to my invention, the method of preparing the paper pilewhich is to be cut and trimmed, where the sheets were of large size, wasto double a num ber of the sheets over as is shown at 7 in Figure 3 tofacilitate handling. Then the folded bundle was inserted through thespace 9 between the hold-down and the table top, and then opened outflat. Then the flattened stack was jogged against the side gauge andback gauge to even up each successive addition with the preceding ones.

Since it is desirable that the cutting stroke which would allow the lastfolded group of sheets to be straightened out and jo god to even theedges of the pile. As the piFe grew, this unfolding and jogging becameincreasingly diflicult, thus slowing up the operation of getting thepaper pile ready for trimming and cutting.

The operator and his helper alternated in the pile building and in thejogging of the pile, and when this was accomplished-the machine operatorcompleted the trimming and cutting, the helper being idle.

Referring now to Figure 1, the table 2 is shown extended angularly tothe right, forming a second table top 10. The table top 10 has at oneedge, a fixed side gauge 11, and at the end of the table top 10 furthestto the right, as shown, there is a movable end gauge 12. The two gauges11 and 12 form a right angle against which a pile of paper stock may bejogged. With the extension 10 of the table, the process of laying up thepile and jogging it into an even edged pile of predetermined height is amuch easier matter for the helper than with a machine which requiresfolding of the sheets and ushing them under the clamp. V The foldedundles 7 may be easily opened out on the table top 10 and jogged mtoposition to form the usual pile of stock. The helper can easily jog thepile 13 of paper stock into position on the table extension 10 withoutbeing cramped by the proximity of the clamp.

With the pile 13 of paper stock in the position shown 1n Figures 1 and2, the operator from the front of the cutter closes the switch to themotor actuating. mechanism, which moves the aper stock pile to the leftonto that part of the table indicated at 2, in front of the movable backgauge 6.

Mounted on the under side of the table extension lOis a reversing motor14 which has a driving pulley 15. The table extension 10 has a slot 16extending from the, outer end of the extension 10 to a position withinthe line of table top 2. Parallel with this slot 16 there is atraversing screw 17, which is journaled at its forward end in athrust-bearing 18, and at its drive end in a bearing 19. In line withthe driving pulley 15 there, is a grooved pulley 20, connected to thepulley 15 by a V-belt 21.

The movable end gauge 12 has a connec tion 22 extending down through theslot 16 in the table extension 10. This connection 22 engages a nut 23on the traversing screw 17. This mechanism is the usual construction inpaper cutters for traversing the an e.

g ounted at the front and to the right of the center of the cutter table2 I have indicated a three button switch 24. One button controls theforward movement of the 'end gauge 12; another controlling its reversemovement, and the third controls the stopping of the movement of the endgauge 12.

Located beneath the extension 10 are a pair of safety stop stations 25,the function of which is to prevent an overrunning movement of the endgauge 12 in either of its directions of travel. Contact between the endgauge 12 and the safety stops 25 is made by suitable stops mounted onthe nut 23; The

stops over-ride and depress the circuit breaker of the appropriatesafety stop station 25.

I have not illustrated the mechanism of this safety circuit exceptdiagrammatically, it'

being of well known commercial types.

The operator, stationedat the front of the cutter 1, can, by depressingthe button marked Forward, move the pile of paper. stock 13 to aposition in front of the back to double back ang' thus disarrange t epile.

When the pile of aper stock is in position on the table 2 in ront of theback gauge, the slip strip 26 is removed and held ready girdinscrtionunder the next pile to be hane a When the pile of paper stock 13 is inposition on the table 2, the next operation is to depress the bottombutton marked Reverse, as shown in Figure 2. The end gau e 12 is thenreturned by ,its traversing mec ani'sm to its initial position, readyfor the building of another pile of stock.

The operators helper, who, with the usual apparatus, would be idleduring the of trimming and cutting'of the pile 0 stock by the operator,now immediately begins the assembly of a new pile of stock, so that whenthe operator of the cutter 1 completes his operations on the previouslpile, he finds a succeeding pile of paper stoc 13 ready to be movedinto position for trimming and cutting by the cutter 1.

In order to prevent any possibilit of the accidental operation of theswitch or moving the end gauge 12 forward and, thereby brlnging aprepared pile of paper stock into collision with either the pile ofpaper stock being cut or theback gauge 6 of the cutter 1, I haveprovided a circuit breaker switch 27 mounted on the rear edge of thetable 2 of *the cutter 1. This switch has a button 28 adapted to bedepressed by a contact 29 carried by the back gauge 6 of the cutter 1.When the back gauge 6 begins to move forward, depressing the forwardcontrol button of the switch 24 will have no effect on the traversingmotor 14 because, as shown in the diagram of the electric circuit, thecurrent flow will be broken by the circuit breaker 27 in the line 30.The operation ofthe forward button of the switch 24 would therefore beineffective.

The mechanism for feeding the back gauge on the cutter table 2 issimilar to that for operating the end gauge 12. Safety stops areindicated to lim1t the travel of the. back gauge 6, and there is alsoprovided a three button switch 31 to control the forward, stop andreverse motions of the back auge 6. The

two panels 32, 33, carrying t e automatic switch for the electricalcircuits of the cutter are mounted in cabinets 34 on the front of thecutter frame 1, as is seen in Figure 1.
